(Updated on 9/6/14) Bipartisanship or libertarianism. Those were the two primary messages from the half-dozen congressional candidates participating in Tuesday’s Arlington Civic Federation candidates forum.

Democrat Don Beyer, the odds-on favorite in the race to replace retiring Rep. Jim Moran (D-Va.), stuck to the “proven, principled progressive” theme of his successful primary campaign, while also promising to work across the aisle.

“Anything I need to get done in my first term will likely have to be done with Republicans,” Beyer said, acknowledging the GOP’s majority in the House and potential future majority in the Senate. “This is a very important reason why I want to run… I want to go there as a strong Northern Virginia Democrat to work across party lines.”

Beyer, a former Virginia lieutenant governor and U.S. ambassador under President Obama, also touted his business acumen as co-owner of his eponymous car dealership chain.

“We need to build a new American economy, based on the deepest possible investments in human capital,” he said, while listing a litany of his progressive positions: support for a national carbon tax, tighter gun controls focusing on criminals and the mentally ill, making “improvements” to Obamacare (the Affordable Care Act), universal pre-kindergarten, marriage equality and immigration reform.

Republican Micah Edmond, a former Marine Corps officer, said bipartisanship and a balanced budget would be his first order of business in Congress.

“I see my campaign as a mission to make the American dream achievable again for all people,” he said. “If elected, my top priority will be to work with Republicans and Democrats alike to [enact] a 10-year economic plan that ends sequestration, allows us to pay down our debt responsibly, balances our budget, reforms our tax code, strengthens our entitlement system and allows us to… [make] direct investment into… education, infrastructure and national security.”

“I’m working hard to earn your vote,” Edmond told the packed crowd. A South Carolina native who served as a senior staffer for members of the House Armed Services Committee after leaving the Marine Corps, Edmond described himself as a “pragmatic problem solver.”

Jeffrey Carson, a Libertarian whose website sports an illustration of a star-spangled porcupine, was true to form as the evening’s prickly firebrand.

A former U.S. Army captain, Carson decried the nation’s “meddlesome, haphazard and dangerous interventionist foreign policy; our failed and unconstitutional drug war; NSA domestic spying; militarized police forces and the erosion of our civil liberties.” He accused Edmond of talking about lower taxes while proposing spending hikes rather than spending cuts, then accused Beyer of ignoring the problem of the national debt altogether.

Carson said he would “strip Congress of its power to overspend” by passing a business cycle-balanced budget amendment to stimulate the economy.

“We continue to allow our politicians to continue kicking the can down the road for another year, another election cycle, another generation,” he said. “Is it scary to face these problems head on? You bet.”

Gerard Blais, a candidate under the banner of the Independent Green party, espoused many of the libertarian ideals of Carson, with a pro-transit and social spending twist. He kept his remarks brief in comparison to his fellow candidates.

“I was inspired to run when, working as an intelligence analyst for the U.S. government, I noticed our flawed strategies continuing to fail abroad,” Blais said in his opening statement. “That’s why I would support an immediate pullout from all wars of aggression and choice abroad. I would also support drug legalization… a massive increase in public transportation, universal healthcare and an elimination of the federal income tax on the first $100,000 of income.”

Blais added a free college education and immigration reform to the list of policies he would pursue.

“As an IT worker, I enjoy a very bloated salary” because we’re not allowing enough skilled workers in, he said. “More immigrants will pay more U.S. taxes.”

Gwendolyn Beck, who’s running for Moran’s seat as an independent, said she wants to help facilitate compromise between the two parties.

“I think everyone is disappointed with the gridlock in Congress,” she said. “The Republicans and the Democrats are not talking to each other. I decided to run because I believe that we need to build badly needed coalitions in Congress.”

Beck, who lives near Rosslyn and describes herself as “fiscally responsible, socially inclusive,” said she is “very concerned about the waste of taxpayer money” and wants to fight for the rights of “seniors, children, women — everybody.”

Also participating in the candidates forum was Libertarian U.S. Senate candidate Robert Sarvis. Democratic incumbent Mark Warner and Republican Ed Gillespie declined their invitations.
